  • the present disclosure provides methods of treating and/or preventing fibrosis in a subject in need thereof, the method comprising administering to the subject a composition comprising 15-HEPE.
  • FIG. 2 shows differences in very low density lipoprotein (VLDL) levels for mice given a single dose of steptozotocin after birth, fed a high-fat diet for 4 weeks, then treated for 8 weeks with vehicle, telmisartan, 15-HETrE, or 15-HEPE.
  • VLDL very low density lipoprotein
  • FIG. 9 shows effects of 15-HEPE compared to vehicle, telmisartan and EPA after 4 weeks in a mouse model.
  • compositions comprising 15-HEPE, and methods of using same for treating and/or preventing fibrosis in a subject in need thereof.

  • the 15-HEPE may be the sole active ingredient.
  • the 15-HEPE may be combined for co-formulation or co-administration with another agent or agents for treating and/or preventing fibrosis. If an additional active agent or agents is/are to be used, the 15-HEPE can be co-formulated as a single dosage unit, or the 15-HEPE and the additional fibrosis therapeutic agent can be formulated as two to a plurality of dosage units for coordinated, combination or concomitant administration.
  • the present disclosure also provides formulations of 15-HEPE and formulations comprising 15-HEPE and methods of using these formulations for treating and/or preventing fibrosis.
  • the 15-HEPE is in the form of an ester (also referred to herein as E-15-HEPE or ethyl-15-HEPE).

  • compositions of the present disclosure comprise one or more pharmaceutically acceptable excipients.
  • pharmaceutically acceptable excipient herein means any substance, not itself a therapeutic agent, used as a carrier or vehicle for delivery of a therapeutic agent to a subject or added to a pharmaceutical composition to improve its handling or storage properties or to permit or facilitate formation of a unit dose of the composition, and that does not produce unacceptable toxicity or interaction with other components in the composition.
  • a pharmaceutical composition according to the present disclosure may comprise one or more of: antioxidants, surfactants, preservatives, flavouring agents, co-solvents, viscosity aids, suspension aids, and lipophilic phases.
  • the fibrosis is associated with non-alcoholic fatty liver disease (NAFLD).

  • an NAFLD activity score is reduced in the subject after administration of the composition.
  • the NAS is reduced in the subject compared to baseline.
  • the NAS is reduced in comparison to a second subject who has not been administered the composition.
  • the second subject has been administered a placebo.
  • the second subject is on fibrosis therapy.
  • methods of the present disclosure cause a NAS value to decrease in a subject.
  • the method further comprises determining a second, lower NAS value associated with the subject after administering the composition for a period of time.
  • NAFLD activity score (d) is reduced in the subject after administration of the composition;
  • the purpose of this study was to examine the effects of 15-HEPE and 15-HETrE compared to vehicle and to telmisartan in a mouse model of NAFLD.
